"My thoughts were, 'I hope no one was in that car like, a baby or an adult or somebody hurt.' And then we came and started talking to the police and fire guys and they said that it was just a lady who had forgotten to put her truck in park and it rolled off into the water. So a simple mistake like that and the truck is gone," said Joe Neisler.

Nobody was in the truck at the time and no injuries were reported, deputies say.
